"It's going to [expletive] up a lot of people," he added. "And it was a bummer because I'm a huge fan and I didn't want to know what's going on. I was like, 'Damn, I didn't want to know that!'"

Momoa, whose character was killed off in Season 1, got the lowdown during a recent visit to the show's set in Belfast, Northern Ireland. He said, however, that he won't be reprising Drogo in the final season.

"I just showed up to see [producers David Benioff and D.B. Weiss] and I just happened to see people on set," the star insisted.

"I haven't been over there in a long time," he explained. "You just want to see your friends and you end up making headlines going, 'Drogo's back!' and I'm like, 'He's dead! He can't come back, it wouldn't work.'"

Momoa had shared photos with Game of Thrones star Emilia Clarke in November. He couldn't help but gush about the 31-year-old actress, who plays Daenerys Targaryen, the queen of dragons and Drogo's widow.

The pair co-starred as Daenerys Targaryen and Khal Drogo in 'Game of Thrones' Season 1.

"Crazy mad insane LOVE for this queen it's truly like bubbles of giggles are in our bellies when we are together," the actor wrote. "It's a shame we don't get to see each other as much as we would like but when we do i feel like a [expletive] KHAL."

Game of Thrones co-stars Kit Harington, Lena Headey, Sophie Turner and Maisie Williams. The show has yet to set a premiere date for its eighth and final season.
